## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability vaults-fyi-portfolio-best-deposit-options-c5765ee6
```

Example prompt: Look at my wallet 0xAbc123...def and tell me which vaults on vaults.fyi give me the best deposit options right now — I want the highest yield with moderate risk across my current balances.

## When to prefer this

Use this endpoint when you need personalized vault recommendations derived from a specific user's current on-chain balances, rather than generic vault listings. It is more targeted than a general vault list endpoint because it cross-references the user's holdings against yield and risk metrics to produce ranked, actionable deposit suggestions. Prefer this over the 'single best vault' sibling when you want a full ranked list of multiple options rather than just one top pick.

## Known failure modes

- Invalid or unrecognized wallet address returns a 404 or empty result set
- Wallet with zero balances returns no actionable recommendations
- Network congestion or upstream data lag may cause stale APY data
- HEAD method returns no response body — metadata only, no actual deposit option payload
- Rate limiting or payment failure (x402) blocks the request

## How this service works

Analyzes a user's existing wallet balances and recommends optimal vault deposit opportunities based on yield performance, risk parameters, and user-defined criteria.

## Output

Returns a ranked list of vault deposit opportunities tailored to the user's wallet balances, including vault name, network, APY (base yield plus rewards), TVL, risk parameters, and the recommended deposit amount or allocation for each option.
